Product Details

【Product Introduction】

The product is made from renewable resources such as rice husk and straw using the carbon dioxide acidification process to produce the EV series of bio-based silica (also known as bio-based white carbon black / rice husk silica / rice husk white carbon black). It is a white, non-toxic, amorphous micro pearl substance. The product is an important inorganic silicon compound with excellent properties such as porosity, easy dispersion, light weight, good chemical stability, high temperature resistance, non-combustion, and good electrical insulation.

【Application scope】

The EV series of bio-based silica is produced by precisely adjusting the aggregate particle size and the basic particle size during the production process. It is a new generation of highly dispersed bio-based silica that combines high dispersibility, high reinforcement and low hysteresis. The EV series of products have a unique structure and can be used in engineering tires, high-end car tires, and high-end daily chemical products. After this product is filled with rubber, it can be used in all-steel and semi-steel radial tires, and the filling quantity can be 10-120 parts.
